The QR code has gained popularity in recent years, given its superior readability and storage capacity compared to more traditional barcodes (UPC barcodes). Given a smartphone’s camera can be used to scan barcodes, now millions if not billions of consumers have the equivalent of a barcode reader in their pocket – giving the consumer easy access to a wealth of information – including product details, coupons and yes – mobile-web surveys! When a QR code is used to launch a QR survey, the mobile-web survey URL is encoded into the QR code. When scanned, the QR Survey code automatically launches the mobile device’s browser and directs the consumer to the online survey. The reason it’s referred to as a mobile-web survey, opposed to a typical online survey, is because a mobile browser is being used to launch the online survey. Online surveys are usually accessed through a PC’s browser, opposed to a mobile device’s browser. There are technical considerations when deploying mobile-web browsers given the bandwidth of a wireless device as well as the resolution of a smartphone’s smaller display. Online survey providers who claim to provide mobile-web survey technology should be optimizing their online survey technology to detect the mobile device that is accessing the online survey so that the survey can be properly rendered for the that particular device’s screen size, resolution and mobile browser (e.g. iPhone’s uses the Safari browser whereas Android a generic browser, until Chrome becomes available).
History of the QR Code:
The QR code stands for “Quick Response Code” and was originally invented by Toyota to help track automobile parts. Although its original use was intended for industrial applications it has become the barcode of choice for a variety of marketing purposes. The QR code is a type of matrix barcode (two dimensional). The QR code is unmistakable given its unique square shape that is made of square dots on a white background. Virtually any kind of data can be stored on a QR code. There are four standard types or modes available, but there are also extensions that can be used to extend the storage capabilities.
